“…For example, Wu et al [9] reported that commercial pure Ti with HLS fabricated by asymmetric rolling followed by annealing possesses the strength of ultrafine-grained Ti and a ductility slightly better than that of coarsegrained Ti, which is hitherto believed impossible. A similar HLS-induced strengthening and toughening effect has also been reported in other engineering metals and alloys, including 304 L/316 L stainless steel, [19,20] high-entropy alloy, [21,22] and aluminum alloy. [23] To date, most research on HLSed materials has mainly focused on their mechanical performance and deformation mechanisms.…”

“…However, the hard matrix still exhibits a severely deformed nanostructure elongated to the RD, consisting of ultrafine/nanograins containing a large number of dislocations. In this way, the soft lamella was rigidly constrained by the surrounding hard matrix, forming a near-ideal HLS, [14,19] as schematically illustrated in Figure 3j. Such high mechanical contrast and unique heterogeneous lamella geometry will produce a significant strain incompatibility between the coarse and fine grains during deformation, which results in the heterodeformation-induced (HDI) hardening effect and thus greatly benefits the mechanical properties.…”

“…[3][4][5] In this respect, different types of heterogeneous structures have been developed, including bi/ultimodal grain structures, [6][7][8] heterogeneous lamella structures (HLS), [9,10] harmonic (core-shell) structures, [11,12] gradient grain structures, [13,14] and laminated structures. [15][16][17][18] Among all reported heterogeneous structures, according to recent reviews by Wu and Zhu et al, [19] the HLS, consisting of soft micrometersized lamellae embedded inside a hard matrix of nano/ultrafinegrained lamellae, is particularly effective and has been considered as a near-ideal heterogeneous structure to achieve an optimal strengthductility synergy. For example, Wu et al [9] reported that commercial pure Ti with HLS fabricated by asymmetric rolling followed by annealing possesses the strength of ultrafine-grained Ti and a ductility slightly better than that of coarsegrained Ti, which is hitherto believed impossible.…”

The strategy of designing heterogeneous structures has emerged as a new tool in avoiding the prominent strength–ductility trade‐off dilemma in metallic materials. However, methods to reproducibly synthesize heterostructured materials with effective microstructural control are still elusive. Herein, a highly reproducible method based on conventional accumulative roll bonding (ARB) and postannealing is proposed for designing heterostructured Cu samples with precisely defined heterogeneous lamellar structure (HLS) wherein the size, volume fraction, and spatial distribution of coarse and fine grains can be accurately controlled. An optimal heterogeneous lamellar microstructure is found which gives rise to a roughly 3 times higher yield strength than that of coarse‐grained Cu and a good tensile ductility of ≈34.7% total elongation. Experimental observations reveal that the unique HLS induces strong heterodeformation‐induced hardening and promotes dislocation accumulation, leading to the observed exceptional strength–ductility synergy. This novel fabrication method is applicable to a considerably larger number of metal systems and can be utilized to further tailor HLS to optimize the mechanical properties of metals.

In this cutting-edge research era, silver nanoparticles impose a substantial impact because of their wide applicability in the field of engineering, science, and industry. Regarding the vast applications of silver nanoparticles, in this study, the crystallographic characteristics and nanostructures of silver nanoparticles extracted from natural resources have been studied. First, biosynthetic silver nanoparticles were synthesized using the Pathor Kuchi leaf (PKL) extract as a mediator, and their crystal structures and characteristics were analyzed by UV–visible absorption spectroscopy, Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), and energy-dispersive X-ray (EDX) analysis. The average crystallite size of the synthesized silver nanoparticle was determined to be 20.26 nm, and also the lattice strain, intrinsic stress, and dislocation density were measured to be 2.19 × 10–3, 0.08235 GPa, and 3.062045 × 10–3/nm2, respectively. Further, the prepared sample of silver nanoparticles shows four peaks in the X-ray diffraction pattern, which correspond to the (111), (200), (220), and (311) face-centered cubic (FCC) crystalline planes. The outstanding finding of this work was that when the lattice parameters of the precursor were increased, the volume of the material did not considerably change, but the particle size decreased. Second, it was clearly demonstrated that this straightforward method is a clean, cost-effective, environmentally sustainable, nontoxic, and efficient route for the synthesis of silver nanoparticles (Ag NPs) using PKL leaf at ambient temperature, which also satisfies the green chemistry requirements. Finally, this study demonstrates the scope for the production of silver nanoparticles using low-cost natural resources.

Spark discharge optical emission spectrometry is one of the most effective methods to accurately determine the chemical composition of stainless steel and other metal materials. However, when the thickness of the sample to be tested is less than 3 mm, the test stability of this method decreases and the sample is at risk of breakdown. In this paper, we studied the surface morphology of the excited samples by optical microscope and scanning electron microscope, and analyzed the reasons that affected the testing instability of thin samples. An auxiliary thickening device was proposed to improve the excitation stability of this method, and we realized the efficient determination of key chemical components in thin stainless steel samples. Accurate and stable test results were obtained for 304 stainless steel thin samples with different thicknesses of 1 to 3 mm.
